In September of 626 AD (the ninth year of Wude), Emperor Taizong, who was at the beginning of his reign, said, "The king regards the four seas as one family, and all of us are sons in his territory."

In 627 AD (the first year of Zhenguan), he said, "I make the world my home."

In 644 AD (the 18th year of Zhenguan), he said, "Yidi is also popular, and its feelings are different from those in midsummer. People don't have to be suspicious of different people when they are suffering from moral problems. Gede Zeqia, then the four barbarians can make it like a family; If there are many suspicions, the same flesh and blood will inevitably become enemies. "

In 647 AD (twenty-first year of Zhenguan), it was said: "Since ancient times, China has been valued, and I have been indifferent to it, so I have always loved it as my parents."
